JAMES ROBERT WRIGHT, OF PORTLAND, OREGON.

VEHICLE-SPRING.

SPECIFICATION forming part of Letters Patent No.338,905, dated March 30, 1886.

(No model.)

To all whom it may concern:

Be it known that I, J AMES ROBERT WRIGHT, of Portland, in the county of Multnomah and State of Oregon, have invented a new and Improved Vehicle-Spring, of which the following is a full, clear, and exact description.

The object of my invention is to provide a new and improved vehicle-spring which is very elastic with a light or heavy load, is strong and durable, simple in construction, and is so constructed that the spring-plates are not subjected to any lateral or torsional strain, which spring at all times regulatesitself to the weight imposed upon it.

The invention consists in the construction and combination of parts and details, as will be fully described and set forth hereinafter, and then pointed out in the claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure l is a side view of my improved vehicle-spring. Fig. 2 is a plan view of the under side of the same. Fig. 3 is a cross-sectional view on the line :0 as, Fig. 1. Fig. 4 is a cross-sectional view of my improved shackle. Fig. 5 is a side view of the same. Fig. 6 is a top view of the same. Fig. 7 is a detail view of the bolt or pin in said shackle. Fig. 8 isa plan view of the under side of the lower sec tion of the shackle. Fig. 9 isa detail sectional View.

This invent-ion relates to springs which are mainly adapted for use on side-bar vehicles, and the springs will be described as used with such vehicles; but they can be used on other kinds of vehicles as well.

The steel lever A is curved throughout its entire length, has its inner end squared, and is tapered from said inner end to its outer end, which is provided with the eye A for coupling the end of the lever with a vibrating shackle.

The inner end of each lever A is passed into a box, B, placed and held against the bottom Cof the vehicle body or box in a manner that will be described hereinafter.

Each box B has an open and a closed end, and the inner end of the lever A rests against the closedend of said box, the bottom of the box being open. The lever A,passing through One or more flat spring-plates, D, are bolted to the under side of the end part, A, of each lever A, and said flat spring-plates are curved in the same manner as the spring-plates of wagousprings of the usual construction. To the free end of each spring-plate D the end of one of a series of spring-plates, E, is pivoted or connected in the usual manner, which plates E have their opposite ends bolted to the top of the corresponding box, the ends of said spring-plates E being between the top of said box and the under side of the bottom 0 of the wagon body or box.

At the open end of the box B the lugs F project downward from the side edges of the box, and on the bottom edges of said lugs of each box the clip-yoke G is placed, through the ends of which the bolts H are passed, which are also passed through side lugs, I, on the upper sides of the box, the tops of the side lugs, I, projecting slightly above the top of the box B, so that the tops of said lugs I and the tops of the springs E are flush. A rubber band, G, is placed on the clip-yoke G, below the lever A. The bolts H are passed through apertures in the bottom of the box or body of the wagon, and through a plate, H, on the top of the floor or bottom of the vehicle body or box. Nuts H are screwed on the ends of the bolts below the clip-yoke G. If desired, a U- shaped bolt may be used.

A tongue, J, projects from the upper surface of the end A of each lever A through a slot, J, in the top of the box, through slots in the springs E, and into a mortise on the under side of the bottom 0 of the vehicle body or box, which tongue closes the end of the box B against dirt, dust, 8m.

As shown in Fig. 1, the under sides of the rear orinner ends of the levers A and the upper sides of the closed or corresponding ends of the boxes B are curved slightly, so that for light loads the springs can bend on the under sides of the levers and on the tops of the boxes nearly up to the bolts holding the ends of the springs on the levers and boxes. As previously stated, the tops of the end parts, A, of the levers are also rounded, so as to work easily on the under sides of the tops of the boxes B.

The lugs I give the boxes Bvery broad bearings on the under side of the bottom of the wagon box or body.

In each eye A of each lever A a U-shaped shackle, K, is pivoted by a bolt. K, which shackle is formed of three parts, of which one part is held on the end of the lever A by the bolt, as stated; another part is held on the under side of the side bar of the wagon-body and consists of a plate, N provided with a downwardly-projecting semi-cylindrical neck or projection, M, having a longitudinal recess or cavity, 0, forming a socket, and the slot P the downwardly-projecting stem Q,

in the bottom, which slot is at right angles to the longitudinal axis of the recess. In said recess is placed the cylinder R, which can rock on its longitudinal axis, and is provided with having its lower end screw-threaded, said screw-threaded end being screwed into the top of the lower section of the shackle. If desired, a -half-ball may be used in place of the cylinder; but I prefer to use a cylinder. The bottom sections of the shackles K can swing on the ends ofthe levers A, and can rock on the rounded lower ends of the projections M. A

The two springs of each set and their levers are placed at an angle to the transverse axis of the vehicle-box, so that the outer ends of the levers A will be on the same transverse.

line of the vehicle-box, which transverse line is at right angles to the longitudinal axis of the box.

A vehicle provided with my improved springs rides very easily with a light or a heavy load.

Each spring is independent of the other, and each spring can be removed or replaced without disturbing the other. The springs canbe a box, ofa lever having one end in said box, 1 I flat spring-plates secured to the bottom of that part of the lever in the box, cured on the top of the box, the ends of the springs secured on the box and on the lever being jointed together, substantially as herein shown and described.

2. In a vehicle-spring, the combinatiomwith the box B, of the lever A, having one end in said box, the tongue J, projecting upward from said lever through a the springs D, secured to the end part of thelever A, and the springs E, secured to the top of the box B, substantially as herein shown and described.

3. In a vehicle-spring, the combination,with the box B, having the side lugs, I, of thelever A, having one end in said box, G, the bolts H, passed through the lugs I and the clip-yoke, and the springs D and E, secured to thelever A and the box, substantially as hereinshown and described.

4. In avehicle spring, the combination,with the box B, having the lugs I and F,of the clipyoke G, the bolts H, passed through the lugs I, and of thesprings lever Aand the box B, substantially as herein shown and described.

5. In a vehicle-spring, the combination,with the box B, having the side lugs, I, the tops of which project above the top edges of the box B, of the springs E, secu red on the top of the box B between said lugs I, the lever A, having one end in the box B, the springs D, socured to that end of the lever A'within the box B, the ends of the springs D and E being jointed. together, and of bolts passed through and springs seslot in the top of thebox,

the clip-yoke D and E, secured to the the lugs I, for holding the box B to the under side of the vehicle-box, shown and described.

6. The combination, with a plate provided with a neck or projection having a cavity or recess, of a ball or cylinder in said recess,and provided with a screw-stein projecting from substantially as herein the bottom of the neck or projection, and of a shacklepiece in which the said stem isscrewed, substantially as herein shown and described.
